Question

How are heat and temperature related?

Answer 1

Hint: Apply the concept of Thermodynamic analysis of heat transfer. Temperature and heat are closely related concepts with precise definitions. The heat is referred to the sum of the kinetic energy in the molecules of a body and the temperature is the measurement of heat in a body.

Complete step by step answer:
Another name of heat is thermal energy and it is measured in joule. heat is the total energy of the motion of the molecules inside the object or particle or we can say the heat is thermal energy transferred from a hotter system to a cooler system.
Temperature is measured in degrees Celsius and Kelvin. The temperature is nothing but the measurement of heat in a body. In simple words, the temperature is a measure of the average kinetic energy of the atoms or molecules in the system. We can say the more heated an object is there higher the temperature the object will have. Hence, when the collective kinetic energy of a body increases i.e when the heat increases as also the temperature of the body increases.
The SI unit of temperature is `Kevin` and the SI unit of heat flow is the joule. Normally, the basic difference between heat and temperature is that Heat is the form of energy that transfers from a hot body to a cold body. And the temperature is the degree of hotness and coldness of the body.

Note: To solve these kinds of problems with the help of thermodynamic laws, specially the first and second law of thermodynamics. These laws involve the statement of direction of heat flow and thermal energy flow. In the practical lab to measure the heat flow we use a thermometer.
